WILLIAM HENRY HARRISON MARCUM, OF LOS ANGELES, CALIFORNIA.

WINDOW-SHADE HOLDER AND ADJUSTER.

Application filed September 12, 1916.

To all whom it may concern:

Be it known that I, WILLIAM HENRY HAR- RISON MAROUM, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Window-Shade Holder and Adjuster, of which the following is a specification.

The device forming the subject matter of this application is adapted to be employed for raising and lowering a curtain roller bodily, so that the curtain on the roller at the will of an operator may be made to shield the upper portion of a window or the lower portion of the window.

The invention aims to provide a novel form of extensible carrier in which the curtain roller is j ournaled, novel means being provided for holding the carrier at adjusted lengths.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

offset head 6 in the form of an inverted hook including a depending end 7 A screw 8 or like securing device passes through the outer portion of the head 6 and through the end 7 the screw entering the lintel 3. The screw or its mechanical equivalent serves to sustain and brace the depending'end 7 of the head 6 and constitutes, also, an axle on which is j ournaled a sheave 9 located within the contour of the head 6. A bracket 10 is attached to the lintel 3 adjacent the opposite end thereof, the bracket 10 being constructed like the bracket 4 and being secured to the lintel 3 in a manner like that employed in connection with the bracket 4. The only difference between the brackets 10 and 4 is i 7 that the head of the bracket 10 is wide enough to contain two sheaves 11 located side by side.

The invention comprises a longitudinally extensible carrier on which the shade roller is journaled for rotation. The longitudinally extensible carrier includes a bar 12 which, for the sake of cheapness, may be made out of wood. Mounted on the ends of the bar 12 and extended transversely thereof are U-shaped guides 14, the side portions of which are attached to the bar 12 by means of securing elements 15. The side portions of the guides terminate in approaching fingers 16 and 17 extended beneath the bar 12 at the ends thereof, the finger 17 being distinguished from the finger 16 by reason of the fact that the finger 17 has, as shown in Fig. 4, an upright lip 18 which bears against the end wall of the bar 12 to aid in holding the guide 14 in place.

Mounted to reciprocate between the top portions of the guides 14 and the bar 12 are slides 19 which preferably are made of metal. Each slide at its outer end is equipped with a depending hanger 21. Mounted in the hangers 20 of the slides 19 are the trunnions 21 of a roller 23 on which is wound a shade 22. The inner ends of the slides 19 are provided with depending wings 24 which bear against the longitudinal vertical edges of the bar 12 and aid in directing the movements of the slides 19 as the same are reciprocated longitudinally of the bar for the purposes of adjustment.

The guides 14: are provided with pivot element 25 received in openings 26 formed in the shanks 27 of latches 28. Each latch 28 includes a U-shaped head 29 comprising spring arms 30 and 32, the arms 30 and 32 being flared at their extremities as indicated at 31. The shank 27 of the latch 28 is offset as shown at 33, so that the arms 30 and 32 will exercise their functions in a manner to be pointed out hereinafter.

The slides 19 are equipped adjacent their outer ends with holes 34. The invention comprises a flexible element formed into a depending loop 35 located adjacent one of the stiles 2 of the window frame 1. One end 36 of this loop 35 is carried across one of the sheaves 11 and is extended downwa-rdly, the said end of the loop being mounted in one of the holes 3% in the ends of the guides 19. The other end 37 of the loop 35 is carried across the other sheave 11 and is extended horizontally along the. lintel 3, the said end of the flexible element being carried downwardly across the sheave 9 and be ing connected to the other slide by means of the hole 3% therein. Some means other than the holes 34 may be provided for connecting the ends 36 and 37 of the flexible element to the slides 19. The numeral 38 indicates a flexible element, the upper end of which is connected as shown at H, to the depending portion of the loop 35. The free end of the flexible element 38 is adapted to be engaged by a wire clip 39 held intermediate its ends by a securing device 40 to one of the stiles 2. If desired, the clip may be in the form of a resilient metal plate ll, as shown in Fig. 7.

In Fig. 6 of the drawings, a modified form of the invention is shown. In Fig. 6, parts previously described have been designated by reference characters hereinbefore used, with the suflix a. The distinguishing characteristics of that form of the invention which is depicted in Fig. 6 are that, in the place of the swinging latch 28, a set screw 43 is threaded into the guide 145 the set screw being adapted to coact with the slide 19, it being noted, further, that the depending wings on the inner ends of the slides 19 corresponding to the parts 24 of Fig. 1, are equipped with extensions e2 which project under the bar 12.

In practical operation, referring to that form of the invention which is shown in Figs. 1, 2, 3, 4 and 5 of the drawings, it will be understood that the slides 19 may be moved endwise, so that the depending hangers will cooperate properly with the trunnions 21 of the shade roller 23. When this result has been brought about, the latches 28 are swung laterally on the pivot elements 25. The upper arms 32 of the latches bear on the slides 19, and the lower arms 30 of the latches engage the lower face of the bar 12. The slides 19, therefore, are held to the bars 12, so that the slides cannot change their positions, after having been adjusted. Since the arms 32 and 30 of the latches 28 are flared as indicated at 31, the arms may be made to engage readily with the slide 19 and the bar 12. when the slides are swung on the pivot elements 25.

In connection with the modification shown or the lower portion thereof, the flexible element 38 is disengaged from the clip 39 and is slacked away, whereupon the ends 36 and 37 of the flexible element which includes the loop 35, will travel over the sheaves 11 and 9 in a manner clearly understood by those skilled in the art.

The device forming the subject matter of this application is of few parts and is simple in construction. A minimum amount of material is required in making it, and the structure will be found of peculiar utility in physicians offices, residences and elsewhere, under conditions which call for a bodily vertical shifting of a roller carrying a shade.

Having thus described the invention, what is claimed is 1. In a device of the class described, a bar; guides disposed transversely of the bar at the extremities thereof, the guides including fingers engaging the under side of the bar,'one finger having an upstanding lip engaging the end face of the bar; slides mounted to reciprocate on the bar within the guides, the outer ends of the slides being provided with shade holding means; clamping devices in the guides and coacting with the slides to hold the slides in adjusted positions longitudinally of the bar; and means assembled with the slides for raising and lowering the slides and the bar.

2. In a device of the class described, a bar; guides disposed transversely of the bar at the extremities thereof; slides mounted to reciprocate on the bar within the guides; latches pivoted to the guides and including heads extended transversely of the bar and as my own, I have hereto afiixed my signathe slides, the heads including resilient up ture in the presence of two witnesses. per and lower arms coacting respectively with the slides and with the lower face of WILLIAM HENRY HARRISON MARCUM' 5 the bar; and means for raising and lowering Witnesses:
